Fitness...but mostly because I love bikes. Any and all bikes, but I think the mountain bike is the pinacle of the melding of technology and human power. There's just so much cool stuff going on with mountain bikes.

Great video. I ride because its fun! It makes me feel great for a long time after im done. The fitness, the challenge, it makes me a better person. When i dont ride I get into bad moods. lol plus now that im addicted to it.....i dont have a choice.

While in rehab for alcohol and meth addiction - I considered many possibilities for leading a healthier lifestyle:

GOLF: Too slow, too boring and expensive. Who wants to spend 40% of their time waiting their turn, requiring a near-perfect swing to even succeed at?TENNIS: Been there done that, in High School. Great, for hooking-up with all the Tennis Bunnies(chicks). Finding decent tennis courts becomes a pain...unless you have an expensive club membership.RUNNING: What? Kill my aging knees and jostle my already-strectched organs, only to fall under the monotonous trance of road-induced hypnosis?GYM: The combined scent of everybody's BO is more than enough to make me hurl. I realized long ago that I no longer need weighty "guns" to attract the opposite sex. Lean abs from cardio is 3x as sexy to them now. MTB works your core like no other.MOTORCYCLE: Spend $$$ money/gas on a Harley and get fatter? I choose to run on fat and save $$$ on gas instead.MTB: For me - it's ALL about the bike; the technology, the parts choices, etc. I obsess about bike weight, fit, and riding techniques. I love searching for trails I have never ridden before and write detailed reviews on them, so YOU enjoy them too. I make an annual effort to test-ride every MTB ever made and review them here on MTBR, so you can make the most informed buying decision. Also, I love the endorphin rush while climbing up a 22% grade and the accompanying adrenaline, while I bomb the downhills. I love the fact drugs are no longer needed, because MTB gives me all the "high" I want...and then some, for FREE. I finally selected cycling as my "sport." It took a sober and clean person to come to that realization - but I'm sticking with my choice and will continue riding until I drop...
